Here's a picture of the other cast members.
Nadeshiko is played by co-member Fukuda Kanon (Shugo Chara Eggs, S/mileage) which I first found a little bit odd, but now I have gotten used to her and she actually looks all-right. I don't know the other actors, but most of them seem like fine choices. Tadase is played by a girl, which I find amusing ^_^ But it's also quitet fitting, because Tadase is probably the most girlish manga-boy I have stumbled upon in a long time! XD Haha
I like the girl who plays Rima, she seems cute and then her height fits with the manga character as well ^_~ To the costumes I think the blue ones are a little too bright, or is it just me? The read ones are great – no complains there ;)
The roles of Utau and Ikuto is again played by actors I don't know of. But I think the girl who plays Utau looks okay, but for Ikuto I would have liked a boy with more delicate features (like Hongo Konata!…In my dreams I guess…XD)
Costumes: Every cosplayer's dream!! *O* They look so nice<3
I really look forward to it's release in October, please sub it someone! XD I just need to watch this.
